4 Claims. l

This invention relates to a mobile apparatus or vehicular trailer for handling materials such as dirt, sand, gravel, cinders and the like.

An object of the invention is the provision of an apparatus or trailer of the indicated character which may be used for loading, transporting, unloading and spreading the above-mentioned kinds of materials for various purposes such as surfacing elds for aircraft, and other rough tracts, plots and roadways.

A further object of the invention is the provision of a vehicular apparatus embodying improvements whereby such apparatus may be loaded to capacity with materials such as dirt, sand, etc., and later be unloaded or spread as the apparatus is in translatory movement.

A further object of the invention is the provision of a mobile apparatus or trailer having a body adapted to receive and discharge material of the character mentioned, said body being tiltable up and down, and a conveyor positioned to assist in the loading and unloading of the materials, as the apparatus or trailer travels from one point to another.

With the foregoing and other objects in View the invention resides in the combination, arrangement and operation of the elements hereinafter described and illustrated in the accompanying drawings, in which,

Figure 1 is a side elevational view of a vehicular trailer. embodying the features of the present invention.

Figure 2 is a top plan View.

Figure 3 is a longitudinal sectional View taken on the line 3-3 of Figure 2. 7

Referring now more particularly to the several views of the drawings, it will be apparent, the features of the invention are embodied ln a vehicular trailer adapted to be towed or hauled by a tractor or the like. The trailer includes a running gear IU comprising `a frame or chassis II and front and rear traction wheels I2 and I3 respectively. The wheels I2 are on a pivoted bolster I4 connected with the frame II. A hitch I5 on the bolster I4 may be engaged with suitable means on a tractor for coupling the trailer thereto. The frame IIsupports a rear platform I6 on which is mounted a power unit designated in general by the 'numeral I'I.

There is provided a body I8 having a bottom I9, side walls 2U and a back wall 2 I, and said body is open at the front from the bottom all the way to the top as shown. A shaft 22 is journalled on the frame II in advance of the platform Il and at the rear of said frame. The shaft 22 is 4disposed transversely at a right vangle with respect to the longitudinal axis of the frame. The shaft 22 extends through bearings 23 on the back wall 2l so that the body I8 is tiltably mounted for up and down movement within and with respect to the frame II. The body I8 thus constructed, mounted and arranged, may function as a large scoop when tilted forwardly and downwardly as indicated in dotted lines in Figure 1. The bottom I9 has a scooping blade 25 secured thereto along its front end, as at 26. The blade 25 serves to scoop material such as dirt, sand, gravel, when the-body I8 is properly tilted and the trailer is travelling forwardly.

In order to tilt the body I8 for the purposes stated there is provided suitable means such as a hydraulic system conventionally shown and not specically claim'ed herein. The system includes a pump 21 on the platform I6. Piston cylinders 28 are connected in the system with the pump. The cylinders 28 are on opposite sides of the frame II respectively and each cylinder 28 has' its lower end pivotally connected with the frame, as at 29. The upper end of the piston rod 30 associated with each cylinder 28 has its upper end pivotally connected, as at 3|, with the adjacent side wall 20 of the body I8. When the piston rodsy 30 move upwardly, the front end of the body I8 moves upwardly causing the body I8 to be raised from a previous position to another position with its bottom I9 disposed at the desired inclination, or disposed approximately horizontal, as shown in Figure 3. Conversely, when the rods 30 move downwardlythe body I8 is lowered at the front end with the bottom I8 tilted downwardly and forwardly at the desired scooping angle, or so as to discharge material from the body I8 spread `over the area to be surfaced with the material,

In order to assist in loading the material into the body, and to assist in unloading the material from the body, and to spread the material as it is being unloaded, there is provided a conveyor 32. The conveyor includes a suitable rigid frame 33, which is substantially rectangular and has inner bracing. The side members 34 of the frame have sleeves 35 on their lower ends respectively. The upper ends of the members 34 are connected with bearings 36 by adjustable connections 3'I`respectively. A shaft 38 is supported by the bearing 36. Sprockets 39 are fast on the shaft 38 near its ends. A shaft 40 is supported by bearings onv the side walls 20 of the body I8. The shaft 40 extends through the sleeves 35 on the conveyor frame 33. The shaft 40 is located 3 at the front of the body I9, and above but near the bottom I9. The shaft 40 has a sprocket 4I fast thereon near the opposite ends. Thus there is one sprocket 39 and one sprocket 4I at each side of the frame 99. A chain 42 encircles the sprockets at each side. Secured to the chains l2 and extending transversely. with respect to thelongitudinal axis of the frame 33. is a series of flights or slats These flights or slats are spaced with respect to each other and are pitched outwardlyl with respect to the chains I2.

In order to transmit motion to the chains l2,

there is provided a chain Il which encircles sprockets 45 and 46 fast on the shafts 22 and I9 respectively. The shaft 22 is geared to and driven by the engine of the power unit |1.- It will therefore be understood the conveyor 32 is operated through the intervention of the shaft 22, sprocket B5, chain 44, sprocket 49, shaft III, sprockets 4| and 39, and chains 42. By reversing the engine of the power unit l1, the aforesaid driven parts will lalso operate reversely, and as a consequence the o 'ananas on an axis extending transversely to the longi operating elements 43 will travel reversely, or in a clockwise direction as seenV in Figure 3. The reverse operation of the conveyor 32 is for assisting in unloading the material from the body I9. The direct operation of the conveyor 32 is for assisting in loading the body I8 to capacity.

In order to'swing the conveyor, or to adjust-it 'progressively to various angularities in either direction with respect to the body i8 there is provided means included in the, hydraulic system aforesaid. Said means consists of a cylinder 41 on one side of the frame Il; One end of the cylinder 41 is pivotally connected, as at 48, with the frame il. The piston rod associated'with the cylinder 41 is pivotaliy connected, as at 49, with having a bottom, sides and a back, and open at 4the front, said body being tiltable up and down tudinal axis of the frame, and an endless conveyor tiltably mounted at the open end of vsaid body for movement. between a position approximately parallel to said bottom and a position approxi-,- mately perpendicular to said bottom, said con- .veyor being reversely operable for aiding in loading material into said body or unloading material therefrom during translatory `movement of the apparatus.v

2. A mobile apparatus 'as set forth in claim 1, wherein the conveyor is mounted on and movable with said body.

3. A mobile apparatus as set forth in claim 1.

wherein a shaft is supported on said body near shaft, said shafts constituting parts of the means one end of an arm 50 whose other end is rigidlyy I connected with an extension on one of the sleeves 35, as shown in Figure 2. L

Having thus described my invention, what I claim as new and desire to secure by Letters Patent, is:

1. A mobile apparatus including the combinal tion of a frame having traction wheels, a body for driving the conveyor.
